I'm struggling to get going with this device and its multiple partitions.
I got the device with the Linksys 220.127.116.11728 firmware on it so I didn't reflash it with that or any other Linksys firmware (assuming that if current partition is 18.104.22.168728 than the other one is at least 22.214.171.124978, which is required to upgrade to 126.96.36.199728) -- and maybe that's the reason for my problems.
I got the customized LEDE image running on the device at the moment, but my attempts to use sysupgrade either from Luci or from CLI fail:

So, my questions are:
- How to return to stock to reflash the latest Linksys firmware twice to make sure I start from a clean slate? Luci sysupgrade rejects the Linksys firmware and I'm afraid to use drastic measures like mtd without having the exact command to run.
- If non-working sysupgrade on this device is a known issue, what's the exact command for mtd and should I use the sysupgrade.tar or factory.bin with mtd?
Please help, I got this fantastic device, but it's my first device with multiple partitions and I'm struggling with that.
